1 The competent authority shall require that,
                                 prior to beginning work on a ship, seafarers hold a valid medical
                                 certificate attesting that they are medically fit to perform the duties
                                 they are to carry out at sea.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 2 In order to ensure that medical certificates
                                 genuinely reflect seafarers’ state of health, in light of the
                                 duties they are to perform, the competent authority shall, after consultation
                                 with the shipowners’ and seafarers’ organizations concerned,
                                 and giving due consideration to applicable international guidelines
                                 referred to in Part B of this Code, prescribe the nature of the medical
                                 examination and certificate.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 3 This Standard is without prejudice to the International
                                 Convention on Standards of Training, Certification and Watchkeeping
                                 for Seafarers, 1978, as amended (“STCW”). A medical certificate
                                 issued in accordance with the requirements of STCW shall be accepted
                                 by the competent authority, for the purpose of Regulation 1.2. A medical
                                 certificate meeting the substance of those requirements, in the case
                                 of seafarers not covered by STCW, shall similarly be accepted.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 4 The medical certificate shall be issued by a
                                 duly qualified medical practitioner or, in the case of a certificate
                                 solely concerning eyesight, by a person recognized by the competent
                                 authority as qualified to issue such a certificate. Practitioners
                                 must enjoy full professional independence in exercising their medical
                                 judgement in undertaking medical examination procedures.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 5 Seafarers that have been refused a certificate
                                 or have had a limitation imposed on their ability to work, in particular
                                 with respect to time, field of work or trading area, shall be given
                                 the opportunity to have a further examination by another independent
                                 medical practitioner or by an independent medical referee.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 6 Each medical certificate shall state in particular
                                 that:
                              
                              
                              
                              
                                 - 
                                    
                                    
                                    
                                       (a) the hearing and sight of the seafarer concerned,
                                       and the colour vision in the case of a seafarer to be employed in
                                       capacities where fitness for the work to be performed is liable to
                                       be affected by defective colour vision, are all satisfactory; and
                                    
                                    
                                    
                                  
                                 - 
                                    
                                    
                                    
                                       (b) the seafarer concerned is not suffering from
                                       any medical condition likely to be aggravated by service at sea or
                                       to render the seafarer unfit for such service or to endanger the health
                                       of other persons on board.
                                    
                                    
                                    
                                  
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 7 Unless a shorter period is required by reason
                                 of the specific duties to be performed by the seafarer concerned or
                                 is required under STCW:

                                       (a) a medical certificate shall be valid for a
                                       maximum period of two years unless the seafarer is under the age of
                                       18, in which case the maximum period of validity shall be one year;

                                       (b) a certification of colour vision shall be
                                       valid for a maximum period of six years.
                                    
                                    
                                    
                                  
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 8 In urgent cases the competent authority may
                                 permit a seafarer to work without a valid medical certificate until
                                 the next port of call where the seafarer can obtain a medical certificate
                                 from a qualified medical practitioner, provided that:
                              
                              
                              
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 9 If the period of validity of a certificate expires
                                 in the course of a voyage, the certificate shall continue in force
                                 until the next port of call where the seafarer can obtain a medical
                                 certificate from a qualified medical practitioner, provided that the
                                 period shall not exceed three months.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                               
                                 10 The medical certificates for seafers working
                                 on ships ordinarily engaged on international voyages must as a minimum
                                 be provided in English.
